The Girl With The Iron Bum

She's the 22-year-old who's backside has made her a youtube sensation. Fitness model Bakhar Nabieva has won a legion of fans for her buns of steel.

The Ukrainian has attracted more than 439,000 views on her latest fitness video, which shows her squatting in front of a camera.

Growing up, Bakhar said she was a very skinny child who was often made fun of.

'So I decided to change the situation, I was tired of people looking at me. I started going to the gym, and had no idea how to build an exercise routine correctly so I just started working on the physical part, and one day I woke up and looked in the mirror and I saw some muscles,' she revealed.
